The one arm et the bow traine 169 is curved in part S0 as not to obstruct the collar or brake drum 159 ot' the peg 157 When the cradle 1611sl raised or turned in the removal or the application ot' the peg' 157 therefrom or there to. most heavily on the brake band 170 when the bobbin or body oil' yarn on the peg 157 is full and gradually more lightly as the body ot yarn around the per; diminishes in quantity and diameter so that the tension needed to be applied on the yarn to revolve the peg 157 and body ol' yarn decreases in more or approximate correspondence with the diminution et the diameter of the body of yarn and the Winding` ot' yarn on the spin die El is etleeted under more or less apprend mately uniform tension.

In preparation tor the commencement of Wording of a cop or pirn or the like on a spindle l et the machine, the dog 139 ot the thread guide carrier 136 being disengaged tronlthe thread ol the screw 113, the thread guide carrier 136 is easily pushed back against the stop collar 151 for the eemnieneenient o'l*l a cop, pirn or the like and the yarn being led to the spindle 3, pressure on the linger plate 104; and movement et the arm 132 to raise the roller 133, by a person n'mkine 'with the machine, enable the catch part 106 to be engaged with the cateh part i653 and the bevel Wheel i' to be engaged and held .in engagement with the bevel Wheel 110 and the spring;` 1l) being treed trom the resistance of the spring,l E2C-l is enabled to press the driven member 15 into and to held it tirmly in engagement. with the driving inember irl so that the spindle $3 shall be revolved with the driving inen'iber 8 and Without risk or :imprevisible risk et slipping; or lost inotion until the formation ot a oop, or pirn or other like body around the spindle 3, either on `the spindle 3 itself or a paper tube or other body thereon as nlay be requisite, trom time to timel` is eoniipleted or until the yarn being Wound breaks or comes to an end. Se lone' as the spindle 3 is revolved the serew 11S continues to be reciproeated forwards and backwards by the eam i119 and beine' turned intermittently to impart throng-h the deny 139 in engagement With its thread, a progressive movement to the thread `ruido carrier l-16 and thread guide 1431 and through the oam track 56 of the Cam 4 9 presenting a plurality oit pairs et sections ot opposite hand ot dillierent extent, gives to the screw 113 successive forward and beekvard traverses Within ditiierent limits and so causes some ot the successive Coils of yarn Wound one over another to overlap and others to :tall short of the ends et the coils rllhe `collar or brake. drum 15S) bears i oriwindings wound immediately before them,

sometimes at one end and sometimes at the other7 so that tliecoilsor windings forming` the y successive taper layers or windings ot "a -cop,npirn or like body .are veryfirmly bound together A,sov .as to be held firmly against shelling olf or uiiwinding by ytheir own weight, as slippery yariissuch as those ofartificial silk, are liableto do unless very -firmly bound.` The yarn being wound receives little'friction `inbeing unwound from the jbodyor form in which it may be preparedfor supply tothe spindle since on the way thereto it is guided by rollers freely. revolving and so not liable to rub it so as to cause injury to any yarn however delicate and Vwhen once wound around the spindle it receives no further rubbing. As soon as the sleeve'137 ofthe thread guide carrier 136 touches andpushesthe stop 1527 the catch part `105 isreleased -and the spring 23 causes thefdriveii member 15`to be disengaged from 'tlie'drivingmember 8 and stopped quickly bythe braking action vofthe forked arm 21 and also disengages the bevel wheel-7 3 from the bevel wheel 110 4which then stops so that, although the screw 113 continues to reciprocate, the progressive movement ofjthe thread guidecarrier 136l andthread guide 1431 stops.

Similarly if; the yarn being wound break or teriniiiate,^the roller 133 and arm 132willk fall tof the right hand as seen in Fig. 4,-'and the arm 132 striking the stop 135 will trip the catch 106v and the spindle 3 and vbevel wheel 110 will'be stopped quickly.

WVlien the broken'or terminated yarn has been pieced or` Connected to thev yarn from unwinding of Vanother body to be unwound and used to supply yarn tothespindle 3, the attendantv yworking with the machine can move the arm 1'l3xc'ariying the thread guide 1431 into a positionawayfrom the spindle 3 where it nolonge'r obstructs free access to the already wound' part of a cop, pirn or other body and so is enabled easily-to coil the yarn thereon so yas to place the knot or piecing behind the taperiiigvpart'or chase of tlie'cop, pirn or the like where it will, not hinder the free yarnf from such cop, -pirn or the like. Y

It will be obvious that the reciprocating movement of the screw 113 and its turning will'c'ause the yarn to be wound first in cylindrical or Vnearly Acylindrical layers or coilsand gradually builds up a conical formation or chase.V

It will bel seenthat the adjustment ofthe stopsy piovidedfor co-operation with or actuation'by they thread guide carrier 136 provides for easy adjustment ,of a head ofv the machine to-foriii a cop pirn or the like l of any length witliin'the capacity. ofA the mechanism and that. the adjustment of one y or both of the studs 57, 61 adjusting the eX- l telit of iiioveinent'o'f oney or both of the arms 123 and the extent ofvreciprocationv of their rate of turning of the screws 113 at one orv both of the sides of the machine enablechaiiges easily to be effected in the diameter and the inclination of the tapering portions or chases of cops, piriis or the, like to be Wound. f

Other advantages Vof the invention will be apparent from the foregoing description i and the drawings.

lt will be seen that variation iii detail may be made in carrying this invention'V into eiiect within the scope of the appended claims.
